INGOT-MOLD.

Application filed February 11, 1915.

- but my improvements may be employed in connection with molds for forming other kinds of castings.

In severa l U. s latters ,Patent heretofore grante'dto me I have shown molds for east ing steel ingots in which provision is made for conserving the heat of the molten metal at its upper portion and for promoting the cooling of the lower portion of the ingot or casting, and. my improvements are especially intended for use in connection with such molds although they may be used in connection with molds of other designs.

U. S. Letters Patent have heretofore been I granted to me for improvements in sink heads or feeders which have been found to be very useful and to assist materially in the formation of sound ingots. Such sink heads were designed to be used a number of times, that is, for forming several ingots and were of such substantial construction that they might be removed from one mold and transferred to another if desired.

The object of my present invention is to provide a feeder or sink head of relatively cheap construction which need be used only once and then be discarded at butsmall expense.

' Another object of my invention is to provide a sink head or feeder which may be inserted in the top of the mold cavity and held therein at any desired elevation.

A still further object of the invention is to provide such a feeder with meansby which it may be very readily attached to and suspended from some part of the mold at the desired height therein.

In carrying out my invention I preferably form the sink head or feeder in sections of suitable material and I provide means, such as wires, suitably attached to the sink head bymeans of which it may be suspended in the mold cavity and held at any desired elevation therein, the outer or upper ends of the wfres being attached to some sultable part of the mold at the top thereof.

Specification of Letters Patent.

' Patented Apr. 2'7, 1915..

Serial No. 7,594.

The mold sections may be secured together in any suitable way, preferably by means of a wire surrounding them, and as a further means for holding the sections in contact with each other I employ plates which are inserted in the corners of the feeder where the joints are preferably made. In some cases instead of employing wires for supporting the feeder I use plates which are let into the corners of the feeder and project laterally therefrom in such position. as to rest upon the top of the mold.

Other features of my invention will be hereinafter more fully explained.

In the accompanying drawings, Figure 1 is a view partly in front elevation and partly in vertical section of an ingot mold with a sink head or feeder embodying my improvements applied thereto. Fig. 2 is a view on an enlarged scale and in top plan of the mold and feeder. Fig. 3 is a perspective view of one form of feeder which may be employed. Fig. 3 is a perspective view of one of the plates employed for connecting the feeder sections at the corners. Fig. 4 shows a front elevation of another form of feeder embodying my improvements showing also by dotted lines how the feeder is supported on a mold. Fig. 5 is a detail view in section showing how a supporting plate may be connected with the feeder and serve also to connect the sections thereof.

The .mold A may be of any usual construction, either a' big-end-up or a big-enddown mold, or a mold having a cavity whose cross section is uniform. The mold walls may also be of well known construction, but preferably constructed or equipped to absorb heat more rapidly from the lower portion of. the ingot than from the upper portion thereof, the neck of the mold a having relatively thin walls with less absorptive qualities thus serving to conserve the heat of the ingot at its upper end. The moldis provided with bails or other'devices B by means of which it may be lifted.

The feeder C, shown in Figs. 1 and 2, may be made of fire claypreferably of the cheapest construction, or of any other suitable material. As shown in these figures the feeder the feeder to receive a wire D which is wrapped around the feeder in the groove the sections need not be very accurate and there may be a space, as shown in Fig. 1, between the outside of the feeder and the walls of the mold. By this construction the feeder may be suspended in the mold cavity at any desired elevation, it being understood that in some cases it is desired to have ingots relatively short while in other cases it is desirable to make the ingots longer. I have thus provided a very simple means for adjusting the position of the feeder in the mold cavity. I may also provide other devices-for attaching the feeder sections,-such as plates 0 entering recesses in the corners of the'feeder which latter may be formed in four sections, as shown in Fig. 2, or in. twosections, as shown in Fig. 3. The inner edges ofthe plate 0 may be toothed, as

shown,vthus serving to better join the feeder sections at their corners." The recesses a may be formed during the process of moldmg and baking the feeder sections and the plates 0 afterward inserted. The grooves to receive the wire D may be 'fplaced at any deslred elevation so that the eeder. may be ,held entirely within the mold cavity or partly above it by the wires D, but in some cases Iprefer to' provide the feeder with plates E in the upper portion thereof which pro ect from the corners of the feeder, as shown 1n Fig. l, and are ada ted to rest on the top of the mold. Such p ates E maybe formed with teeth e adapted to engageteeth '6' formed in the feeder sections and therefore serve to lock'the sections to each other and also 'to'support the feeder on top 'of the mold. If desired the feeder shown in Fig. 4 may be also formed with a groove 0 in which a wire may be arranged to bind the sections together at their upper ends and also to suspend the feeder in the manner.

' before .described.

My invention may be applied to various kinds of feeders, whether for use only once or for use'a number of times. The feature of suspending and adjusting the feeder in the mold cavity is applicable to variousv kinds of feeders. The method of forming projecting into the recesses e. The plates the joints is however especially intended for feeders of cheap construction.

It will be understood that the feeder sections are assembled and joined before they are placed in'the mold and the devices employed for this purpose are simple and inexpensive. The wire employed may be of relatively small gage and is very cheap but very efiiclent.

A wedge W may beinserted between the outer walls of the feeder and the inner walls of the mold cavity to lock the feeder at position desired relative to the height of the mold.

I claim as my invention:

1. The combination with a mold of a feeder or sink head therefor through which the metal is poured and means for suspending the feeder in the mold in different hori-' zontal planes below the top of the mold. I

2. The combination with a mold of a feeder or sink head therefor through which the metal is poured and means for adjustably suspending the feeder in the mold in difi'erent horizontal planes below the top thereof.

3. The combination with a mold of a' feeder or sink head therefor and flexible means for suspending the feeder in the mold. 4. The combination with a mold of a .feeder or sink head therefor and wires attached to the feeder and adapted to be attached to the upper portion of the mold to suspend the feeder therein.

6'. A feeder'made in sections joined at thecorners and'having inserted plates for connecting them and a tie-wire surroundmg the feeder for holding the sections in place.

, 7. A feeder made in sections joined at the corners and provided with toothed plates inserted in recesses atthe corners and engaging teeth therein. 5

In testimony whereof have hereunto subscribed my name.
